Specification of Letters Patent.

Patented June 11, 1907.

Application filed May 7,1906. Serial N0. 315,537.

To 1J/Z 'whom t may con/cern:

Be 1t known that I, EVERETT MINGUs, a

Y Vcitizen of the United States, and aresident of Marshfield, in the county of Coos and State of Oregon, have invented a new and Improved Anchor-Projectile, of which the following is a full, clear, and exact description. This invention is an improvement in proljcctiles adapted, when shot into the ground, to automatically become anchored therein.

The object of the invention is to provide a device of this character, to be shot from a cannon the same as projectiles are commonly shot from shore or on board of ship, to carry a line to any given point.

With this and other objects in view, I have constructed a projectile having in all respects the outward formation of the ordinary projectile, but with arms forming part of the periphery of the projectile7 designed to fiy outward due to the action of an attached line as the projectile is shot and engage in the earth or other matter in which the projectile becomes embedded, thereby forming an effective anchoring means.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a central, longitudinal section of my improvement, on the line 1 1 of Fig. 2, showing the arms in full lines as held in the projectile before being shot, and the arms in dotted position as assumed soon after the projectile leaves the cannon mouth. is a transverse section on the line 2-2 of Fig. 1 g and Fig. 3 is a side elevation of the projectile with the engaging arms released.

Referring to the drawing figures, 1 indicates the body of a projectile of any desired outward shape, but having preferably a long, cylindrical body with a conical end 2. Arranged longitudinally of the body 1 and symmetrical with it, are any desired number of channels 3, three being shown in the present construction. As these channels are of like construction and carry the same form of mechanism, a description of one will suffice for the others. rI he channel 3 is rectangular in cross section with an overhanging lip 4 at its forward end having an inclined under face, as best shown in Fig. 1. The rear end of the channel has as a prolongation thereof Fig. 2'

an angular recess 5 connecting with an alining hole 6 passing through the rear end of the projectile.

PivotallyV mounted on a pin 7 passing V transversely through the channel 3, adjacent to the lip 4, is an arm 8. This arm fits the channel 3 and has its outer face rounded off, forming part of the periphery of the body 1 when the arm is closed, and when closed, a space is left below the under face of the arm of the channel 3, in which is fastened flat spring 9 by screws 10. The spring 9 has an upwardly turned toe 11, forming a stop for the arm and projecting it to the dotted position shown in Fig. 1, when released. The rear end of the arm is downwardly inclined as at 12 and is engaged, when closed, by a trigger 13 fitting the angular recess 5, said trigger having an inclined outer end of a counterpart of the end 12, which has the effect of forcing the arm to the extreme limit of its inward movement when the ends are engaged.

The trigger is connected by a stem 14 passing through the hole 6, said stem being riveted into a disk 15 at the rear end of the projectile and pressed forward by a spiral spring 16 encircling the stem and seated in the recess 5 between the shoulders of the trigger and recess.

For attaching a line to the shell, an eye 1S, through which the line may be passed and tied, is connected to the center of the disk by threading one end of its connecting rod 19 and riveting it over, as shown in Fig, 1.

In using the anchor projectile, it is fired from a cannon on land or ship-board with the line attached. The conical end of the shell is adjacent to the breech of the cannon with the line passed through the muzzle and coiled up at the outside thereof.

As the projectile leaves the cannon mouth it travels a short distance with the line end foremost when it receives the tension of the line which suddenly reverses it, the shell then traveling with the conical end forward; this reversed position is due to the tension of the line retarding the momentum of the posterior end of the projectile.

The tension of the line retards the trigger.

disk while the body of the projectile, being free, travels forward with great momentum and thereby releasing the arms during the flight of the projectile.

IOC

titled to such modifications as fall within the scope of the invention as claimed.

Having thus described my invention I claim as new and desire to secure bvv Letters Patent:

l. The combination of a projectile having a long, cylindrical body with longitudinal channels in the face thereof and a conical outer end, lips overhanging the forward ends of the channels, arms pivoted in the channels adjacent to the lips, said arms being rounded off on their upper faces to conform with the periphery of the projectile, springs secured inl the bottom of the channels having upturned toes forming stops for the arms, and adapted to press the arms outwardly, inclined ends at the rear ends of the arms, triggers having ends of an exact counterpart for pressing on the arms, stems connecting the triggers with a disk at the rear end of the shell, springs for pressing the triggers forward, and an eye attached to the center of the disk for receiving a line, for the purpose described.

2. The combination of a projectile, longitudinally-extending arms pivoted thereto, a plurality of devices longitudinally slidable in one end of the projectile adapted to engage said arms, and means rigidly attached to said devices operable to release the arms, for the purpose described.

3. The combination of a projectile, longitudinally-extending arms pivoted thereto, a plurality of devices longitudinally slidable in one end of the projectile, means forcing said devices inwardly to engage said arms, and means rigidly attached to said devices operable to release the arms, for the purpose described.

4. The combination of a projectile, longitudinally-eXtending arms pivoted thereto, and a disk arranged at the rear end of the projectile and longitudinally movable with respect thereto, for releasing the arms.

5. The combination of a projectile, longil 'a plurality of longitudinal channels in the face thereof, arms pivotally mounted in the channels having their upper faces rounded off and corresponding to the periphery of the projectile, springs secured in the bottom of the channels having upturned toes normally forcing the arms outwardly, a disk at the end of the projectile carrying a plurality of triggers for engaging the ends of the arms to hold them in closed position, and means carried by the disk for attaching a line, for the purpose described.

7. The combination of a projectile having a plurality of longitudinal channels in the face thereof, arms pivotally mounted in the channels, springs secured in the channels, overhanging lips at the forward ends of the channels, forming stops for the arms, a plurality of triggers for engaging the ends of the arms to hold them in closed relation, and means attached to said triggers for releasing the arms.

8. The combination of a projectile having a plurality of longitudinal channels in the face thereof, fiat springs secured in the bottom of the channels, arms pivotally mounted in the forward ends of the channels, overhanging lips having inclined faces adjacent tothe pivotal connection of the arms,'trig gers for engaging the arms, springs for pressing the triggers forward, a stem connecting the triggers with a disk at the rear end of the projectile, and means carried by the disk for attaching a line, for the purpose described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EVERETT MINGUS.
